SPECIFICATION formingpart of Letters Patent No. 406,101, dated July 2, 1889.

Application filed February 6, 1889- Serial No. 298,791. (No model.)

To all whom it may concern:

Be it known that I, HERMAN F. KARTOWITZ, of Donaldsom'in the county of Kittson and State of Minnesota, have invented a new and useful Spring-Axle; and I do hereby declare the following to be a full, clear, and exact description of said invention, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My invention, to be hereinafter distinctly claimed, has for its object the providing an axle for vehicles which embodies such yielding and elastic construction as to overcome and obviate to some extent the shock which would otherwise occur to any person or thing being carried in the vehicle by the passing over rough places or obstructions in the way of the wheels.

In the drawings, Figure 1 is a central vertical longitudinal section of my improved device. Fig.2 is a vertical transverse section on line X X of Fig. 1. Fig. 3 is a plan view, the cap being removed to show the parts of the principal device. Fig. 4 is a plan view of a modified form of the device shown in Fig. 3.

In the drawings, A is the axle, or that part of it which extends inwardly beneath the body of the vehicle from the wheels, the other part of the axle forming the spindle B, which enters the hub of the wheel, being constructed in a piece separate from the axle A. The end of the axle A is constructed with open or bifurcated ends, having side walls 0 0 adapted to receive the endE of the spindle. The inner surfaces of the walls 0 C are each provided with one or more lateral recesses extending from the top to the bottom of the wall, into which the lugs or outwardly-projecting guides F F on the end of the spindle E are fitted, and in which they are adapted to move vertically. The end E of the spindle is constructed with a chamber D, having side walls and a bottom adapted to receive therein the tongue G, projecting integrally from the axle A, and also two elastic cushions H and I, the lower cushion H being preferably about twice as thick as the upper cushion I, the tongue G being so located on the axle A and with reference to the end E of the spindle as to be between the cushions H and I within the chamber D in the end of preferably constructed of rubber, and are of such size that with the tongue G they nearly fill the chamber D, but fit loosely therein, so as to provide for their compression and slight movement. A cap K, having its lower part made of a form and size to fit upon the top of the end E of the spindle, and its upper portion of a form and size adapted to cover the united ends of the axle A and spindle B, is secured to the spindle B by a bolt L, passing vertically through'the cap and movably through apertures therefor in the two pieces of rubber II and I, the tongue G, and the hotthe nut M turning thereon. The cap K is provided with an outwardly-projecting hood N, adapted to serve as a cover or dust-excluder to the hub of the wheel, which is received thereunder, though not shown in the drawings, as the relation of the hub to the spindle is well known. Two pins 0 O, fixed in the cap K, project downwardly therefrom and enter recesses therefor inthe end of the spindle E, whereby the cap is held against twisting or turning laterally.

It will be seen that the end of the spindle E, in connection with the cap K, is so constructed as to have a limited amount of movement vertically within the walls 0 O of the axle A, and-it will be understood that as the wheels pass over obstructions, or any sudden jar is given to them otherwise, the force of the concussion will cause the lower spring H to be compressed somewhat, and thereby the shock on the cushion will be taken off from the axle A and its load, and that the rebound of the spring H will be caught and modified by the superimposed spring I, whereby a sudden or severe motion of the axle A and its load either upwardly or downwardly by-reason of passing over inequalities in the road will be obviated.

In the drawings in Fig. 1 the axle Ais constructed in part of iron and in part of wood, the central part P representing the wooden portion of the axle, which enters the metal part A, and is secured thereto by the bolt R, and in Fig. 4 the axle shown is intended to represent an axle constructed entirely of iron or steel.

the spindle E. The cushions H and I are tom of the spindle B, and is held in place by YVhat I claim as new, and desire to secure by Letters Patent,- is- 1. An axle constructed in two parts A and B, the one entering the other and adapted to move vertically therein, the part A being provided with a tongue G, and the part Bloeing provided with a cap K, in combination with elastic rubber cushions H and I, all constructed and arranged substantially as described.

2. An axle A, having bifurcated ends forming side walls 0 0, provided with one or more vertical recesses in the inner surfaces of the walls, and a tongue G, in combination with an axle-spindle B, terminating in an end E,

having a chamber D, and provided with guides F F, a cap K, secured rigidly to the' HERMAN F. KARTOVVITZ.
